Abstract: 1439582 Making blocks of veneer tubes SCHOCK & CO GmbH 14 Sept 1973 [15 Sept 1972] 6146/75 Heading B3T [Also in Division B5] In a method of making blocks composed of veneer rolled into tubular form, the veneers are successively peeled from a rotating log in a moistened condition, then coiling the veneers to form tubes, which are then dried to remove the moisture excess and the tubes are then arranged in layers and simultaneously applied with adhesive on their outer surfaces to form a block. The peeling and coiling of the cut veneers is effected as described and claimed in copending Application 43239/73 the subsequently dried tubes 6, 6.1, 6.2 &c. are discharged from the drier conveyers 15, 16 into a shoot 18 into a container 20 which is reciprocatable relative to the discharge shoot so that successive layers are deposited in the container 20 glue nozzles 19, 19.1 with jets 22 of glue are located one on each side of the shoot so that the external surface of the veneer tubes are coated with adhesive as they are deposited in the container. The glued stack 24 is then applied to an immersion device 25 and is lowered into a bath of adhesive protecting material and when removed therefrom is subject to a compressed air blast to remove excess protecting material which drains back into the bath. The tube stack or block so formed may be sawn into layers forming honeycombe structure and may be glued together to form continuous strips. In the embodiment shown in Fig. 7 the tubes are supplied to a continuous production device similar to that of continuous casting in which they are supplied to an open sided supporting structure 44, 45, 46 and are sprayed with adhesive as they enter the structure the pre-glued stack being subjected to an air blast 47 to promote drying of the adhesive. The sides 44, 45 of the structure are in the form of conveyers and the bottom 46 is continuously moved downwards away from the walls so that a continuous stack of veneer tubes is produced from the bottom of the structure.

Abstract: 213,243. B³chi, A. March 21, 1923, [Convention date]. Regulating.-In an engine in which the charge is supplied by a compressor 6 driven by an exhaust-actuated turbine 7, the admission of the exxhaust gases to the turbine is controlled by a valve 9 adjusted by the engine governor 5 or by hand through linkwork 8, or by a governor driven by the compressor or turbine shaft, or by a piston device subjected to the pressure in the compress- or in the inlet pipe to the turbine, or by a temperature-responsive device 33, Fig. 5, subjected to the heat of the exhaust gases supplied to the turbine, or by the fuel pump or the stopping or reversing gear, or by combinations of these devices. Valves 11, 12 may be provided for opening the inlet pipe 3 and exhaust pipe 4 to atmosphere. A hand or governor actuated throttle may also be arranged in the inlet pipe 3. In a modification, the governor on the compressor shaft controls both the inlet to the turbine and the inlets to two compressors supplying air and gas respectively. In the arrangement shown in Fig. 5, the scavenging is controlled by varying the time during which the inlet and exhaust valves 25, 26 are kept simultaneously open, the valve cams 27, 28 being arranged on a shaft adjusted axially by the governor 5 or the temperature-responsive device 33. The valve 9 and the throttle 31 in the inlet pipe 3 are so arranged as to keep the pressure in the pipe 3 higher than that in the pipe 4 so as to ensure an effective scavenging.

The following groups are specified in the above formul ; R1 and R2 are methyl, ethyl, propyl, butyl, phenyl, naphthyl, tolyl, or benzyl, or together form part of a cyclopentyl or cyclohexyl ring; R3 is methyl, ethyl, propyl, butyl, phenyl, naphthyl, tolyl, cyclopentyl, cyclohexyl, benzyl or methylol; and Ar is a benzene or naphthalene ring which may be substituted by methyl, ethyl, phenyl, tolyl or benzyl.  The hydroperoxides may be prepared by oxidizing the corresponding methyl-substituted ketone as described in Specification 770,622 and the crude oxidation mixture or the purified hydroperoxide may be used in the process of the invention.  The starting materials may be dissolved in an inert solvent such as pentane, hexane, heptane, iso-octane, cyclohexane, cyclobutane, cycloheptane, benzene, toluene, xylene, cumene, diisopropylbenzene, chloroform, carbon tetrachloride, ethylidene dichloride, ethylene dichloride, methanol, ethanol, propanol, cyclohexanol, acetone, methyl ethyl ketone, diethyl ketone, cyclohexanone, methyl or ethyl or butyl acetate, ethyl methyl ether, di-ethyl or -propyl or -butyl ether and glacial acetic acid.  In the case of acid solvents, such as glacial acetic acid, which exert some catalytic activity, correspondingly less acidic catalyst is used.  Specified catalysts are: hydrochloric, sulphuric, perchloric and phosphoric acids; sulphur dioxide; acid or heat-activated montmorillonites or bentonites, benzene sulphonic acid, p-toluene sulphonic acid, sulphonated phenol formaldehyde resins and sulphonated styrene-divinylbenzene polymers; phosphorus penta- or oxy-chloride; mono-, di-and tri-chloroacetic acids; diatomaceous earth, vermiculite, silica gel, kaolinite, illite, attapulgite, and halloyrite; ferric chloride, boron trifluoride, boron trifluoride-etherate, aluminium chloride, zinc chloride, stannic chloride and magnesium chloride.  The catalyst may be supported on a carrier which may have catalytic activity.  The preferred catalyst is sulphuric acid employed under substantially anhydrous conditions.  The reaction may be effected at temperatures between 0 DEG  and 100 DEG  C.  In examples a solution of m- or p-acetyl-a  : a -dimethylbenzyl hydroperoxide in acetone is added to a refluxing solution of sulphuric acid in acetone, the mixture is cooled and the acid neutralised with magnesium oxide, the mixture is filtered and concentrated under reduced pressure, the solid residue being recrystallized from benzene/hexane to give m- or p-acetylphenol.

Title: Improvements in or relating to the preparation of monocarbamyl substituted piperazines and hydrohalide salts thereof
IPC: C07D295/215
Filed: 1949-03-11
Abstract: Monocarbamyl substituted piperazines of the general formula <FORM:0666420/IV (b)/1> (wherein R represents hydrogen or an alkyl radical of 1-4 carbon atoms and Alk represents an alkyl radical of 1-4 carbon atoms), and their hydrohalides, are manufactured by acylating an alkyl substituted piperazine of the formula <FORM:0666420/IV (b)/2> with a carbamyl halide <FORM:0666420/IV (b)/3> (wherein X represents halogen, e.g. bromine or especially chlorine), and, if desired, subsequently or simultaneously treating the resulting hydrohalide with a strong base to obtain the free monocarbamylpiperidine.  The reaction is advantageously carried out at about 20-100 DEG  C. in the presence of a solvent, e.g. at about 30-50 DEG  C. in an aqueous alcoholic solvent such as aqueous ethanol, or at somewhat higher temperatures in non-aqueous solvents such as benzene, toluene, chloroform, carbon tetrachloride or dibutyl ether.  The alkylpiperazine is preferably used in anhydrous form and in sufficient excess to provide an acceptor for the hydrohalic acid formed.  In this case, when working in aqueous alcoholic solution, the excess alkylpiperazine may be precipitated with acid, leaving (when the starting material is unsubstituted on both nitrogen atoms) a solution of mono- and di-carbamylalkylpiperazines.  The former may be caused to separate by concentrating the solution and removing the last traces of water by azeotropic distillation with benzene or toluene, and may, if desired, be further alkylated by treatment with an alkylating agent (e.g. an alkyl sulphate, sulphonate or halide, or formaldehyde in the presence of formic acid or of zinc and hydrochloric acid).  The products are useful as veterinary filaricides.  In examples: (1) 2 : 5-dimethylpiperazine is warmed with diethylcarbamyl chloride in benzene; (2) the product of (1) is reductively methylated by means of formaldehyde and formic acid. Additional starting materials specified are 2 : 6-dimethyl-and 1 : 2 : 5-, 1 : 2 : 6- or 1 : 3 : 5-trimethylpiperazine; methyl-, ethyl-, propyl-, dimethyl-, di-n- or iso-propyl- and methyl-ethylcarbamyl halides.
